Best customer dervice
best customer service and best response and best replacement when part is not working well. these people actually replaced the oxygen sensor i bought from them on amazon twice with a new same part with same value but unfortunately three of them failed rendering the vehicle not passing smog test.... i would not hesitate to do business with GWA & AA Ignition auto parts over and over again I gave them .3 stars for the superior customer service and the quick response … I would have giving them 5 stars but the part failed three times within one month period so I had to buy a name brand part from another vendor at a higher price without refunding my money …
